What causes Climate Change?
Climate scientists agree that the main cause of climate change is human expansion of the greenhouse effect. A total increase of the quantity of greenhouse gases in the atmosphere. These gases include: Water vapour(H2O): A “feedback” chemical which responds to changes in heat, as the climate arms water vapour increase and thus the chances of condensation and precipitation increase alongside it. Carbon dioxide(CO2): A minor but largely important component of the earth's atmosphere, carbon dioxide is released through natural process such as respiration and volcanic eruptions but also from man made processes through deforestation, land changes and the burning of fossil fuels (i.e oil, coal). Statistically since the industrial revolution we have increased the concentration of carbon dioxide in the atmosphere by a third if not more.. Methane: A hydrocarbon gas produced through natural processes, such as livestock, rice farming, agriculture and the decomposition of waste in dumps and landfill. Methane is far less abundant than carbon dioxide in the atmosphere but is also significantly more active as a greenhouse gas. Nitrous Oxide: Produces through process such as land cultivation, use of fertilizers (Industrial/Organic), the burning of fossil fuels, creation and production of nitric acid. Chlorofluorocarbons: Totally of industrial origin chlorofluorocarbons are a synthetic gas used and created in industrial environments (factories etc.). They are now largely regulated for their significant contribution to climate change and status as a greenhouse gas. On earth recreational and industrial activities has significantly altered the greenhouse in the earth's atmosphere for the worse. Since the industrial revolution carbon levels in the atmosphere have changed drastically. The herding of livestock now in mass production creates higher concentrations of methane gas, which is highly active as a greenhouse gas. Mass burning of fossil fuels, which are now under regulation, has contributed to a large portion of the CO2 in the atmosphere. Climate.nasa.gov. (2016).
